To all ichofm, t may concern :l

Be itknown that I, NATHANIEL S. MoN- non, a citizen of the United States, residingat- Arthur', county of-Dou'glas, and State of Illinois, have lnventedcertain new and useful Improvements in Road Leveling- Devices, of' which the following is a specificaa device of this tion.

section taken on substantially line of` fragmentary top view of of the machine, Fig. 7 is an enlarged transverse section taken on substantially line y--y of Fig. 4 and Fig. 8 is a detail section taken on line zee of Fig. 6.

Thev preferred form of my construction as illustrated in the drawings, comprises a body'or platform l the respective ends of upon the front and rear axles-2 and 3, said axles being supported in wheels 4 a'nd 5 respectively. The front axle 2 is iiiounted for horizontal oscillation for steering, operation of said axle in order to Fig. 4, Fig. 6 is a effect. steering, being effected tlii'ogh the f the,`dri vers Aseat medium of chains 6 'which are connected w ith fixed to the .lower end of the rotatably-mounted steering bar 8. The upper endl of the bar 8 `is provided with the hand- Wheel 9 which may be. engagedr to effect rotation of said bar from a position in 10 which is arranged as shownuin close proximity thereto.

Mounted upon the platform 1 at the forward end thereof is. a motor 11 which may be of 'any approved. design or type, the power shaft 12 of said motor being opera- Appiication mea March 24, 1911.

carried respectively by said` axle.

Arranged at the 'opposite sides'. of the body 1 areelongated scraper'barseach of Which Acomprises the eye-.beam l-(to thefnner side of which is securedl the'scraping `plate' 17 and to. the outer thereof the reinforcing angle-iron 18'. The forward divergfently. disposed ends of'said scraper bars arepivotally' connected with the' forward eld of the the -medium 'of connecting devices each. of which comprises a pair I of links 19 and 20. A eaehlink :19 is pivoted'. at .21v with the forward end of to 'permit of relative swinging `of scraper bars in a horizontal direction.' being so, angular adjustment of the Yscraper said This

The inner extremity of the link .20 "is pivotally con-A tre'mity of said link beingv pivotally connected at 23 withthe corresponding link 19 adjacent the outer extremity thereof. Car.- ried by each of thelinks 2O adjacent the inner extremity thereof is an upwardly extending curvedrbar 24,' the corres ondin'g pivotal point 23 being the center o curvature 'of said member.. Said members-24:

lthe links 19, connection between said .links and said supporting members being `effected by the pins or bolts 25. The members '24e are each provided with a plurality of pin- 25 cop struction evidently affording" means for securing the inner extremities of the links 19 in various angular positions and vhence thementioned. Vlith this order to effect such ,adjustment L ofthe scraper bars, it is only the pins 25 and to' adjust the links -19 Vto properly position said scraperbars where .upon said pins may again beinserted to lock tion of' adjustment.' i

The rearward ends of the scraper;4 bars are connected by a sectional nected at.22 with the body 1,'the` outer-ex` serve to support the inner extremities -of' spaced perforations for 'engagement by -the erating' therewith, such conrequired to remove said links and hence said-bars in their posi;

The inner extremities of said seet-ions 26 and 26 are connected with'chains'29, as shwn in Fig. 5,

said chains 29 being connected at their up per, extremities with apulley 30 suspendedv in the b ight of the cham 31; the rearwardextremity of said chain 31 being fixed as at 32 with the rearward extremity of an extension 33o'f the body 1, the opposite ex- .trennt-5 7 34, of' said chain 31 being wrapped.

observed, that byf'rtat-ing the shaft 35 to eti ect the vw'indingjor unwinding 'of the chain 31, the pulle 30`jiriaybe-vertically adjusted and hence te rearward extremities of tlie Extending between the'lbir' endslef the 39 to the 'respective ex.; tremit-ies o f -Which said chains are secured intermediate their extremities as shown- As .will lie-observed, the "lower ends of the chains? 29 depend diver-- Vgently from said bar '39. This being so, upon iipwa-rd movement of the pulley 30 as in the manner justdescribed, said chains 29, in being correspondingly moved upwardly, will tend to assume a vertical position Wit-h the result that the inner ends of the connecting sections 26 and 26 will be rocked upwardly andhence the scraper bars angularly rocked relative to the surface of the ground. This being so,-npon upward drawing upon the chains 29, with the-inner ends of the connectin sections 26 free, anguiar adjustment of t e scraper-:barsin the manner permitted by the links 19 will 4be effected. 'The bar 39, however, as will be observed, serves to limit 'such --adjustment of the'scraper'bars'through' the medium of the chains 29, since upontli'e latter assuming a vertical'position, angular adjustment of t-he scraper bars by said chains will cease. If

' desired the sections 26 and 26 may be rigidly connected, so as toform a rigid connecting member, by the 'pin or bolt 40 which is adapted to engage registering perforartions 41 and/41 provided in the sections 26 and 26 respectivel' as' clearly shown in Figs. v5, 6 and 8. -A so, saidseetions may bc locked in angularly disposed positions through themedium of said pin by reason of the provision of a second perforation -t-l in t-he section 26, said perforation 4l being brought into registration with the perforation 4l of the section 2 6 when said sections A26 and 26 are rocked to their angular positions' by the chains 29.

Arranged at the rearward and of the body 1 medially thereunder, is a chain 42, the rearward bifurcated end thereof being connected with the connecting member formed by the sections 26 and 26 through the medium of eyes 43 provided atthe respective ends of said member. The .forward extremity of the chain 42 is secured to a `vertically extending shaft 44. which is niountellcentrally in the-body 1, the lower extremity of 'and' the upper end thereof in a t'riuisrersely extending bearing ii1eml ei .46.

Provision is also made lor effecting the operative width of the device and for elevating the scraper bars to inoperative position if desired, all adjustments being adapted to be effected from a' position upon the body ofthe device, The rearward ends of the scraper bars, as clearly shown in Fig. G, terminate in spaced relation inV order to permit ot the passage of lumps of earth or other solid matter which may be entraj'iped between the scraper bars, said ends, however, terminating in such a manner that the-path of one will overlap'that of the other so that the entire 'surface of the road' will be acted upon.

employed in their stead. lVith' the excep tions noted, the constructions shown in Fig." 2 and in the remaining figures are identical hence no further description isneeded lof the former".

A machine ot the construction as setf'forth. is durable and economical, and the same'r is of great el'liciency in operation. e

YWhile l have illustrated and described the preferred construction for carrying my invention into effect, this is capable of variation and modification without. departing from the spirit oit' the invention. I, there- 4 e pre'- eis-e details ot construction as set forth, but

t'oie, do not wish to be limited to the desire to avail myself of such variations and mmliliealions as come within the scope ot the apj'lended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:
